Question

You need to borrow some money, so you ask your mom or sister. Your mom says that if you roll a 1 or a 2, she'll give you 5, otherwise she'll give you 1. Your sister says if you roll an odd number, she'll give you 5 and an even number, she'll give you 1. What is the probability of getting 5 if you ask your mom and then your sister?

1) 1/6
2) 1/3
3) 1/2
4) 2/3

Answer 1

The probability of getting 5 when asking your mom and then your sister is 1/6.

Step-by-step explanation:

To find the probability of getting 5 when asking your mom and then your sister, we need to determine the probability of each event separately and then multiply them together.

First, let's look at the probability of getting 5 from your mom. She gives you 5 if you roll a 1 or a 2, which means there are 2 favorable outcomes out of 6 possible outcomes. So, the probability of getting 5 from your mom is 2/6 or 1/3.

Next, let's consider the probability of getting 5 from your sister. She gives you 5 if you roll an odd number, which means there are 3 favorable outcomes out of 6 possible outcomes. So, the probability of getting 5 from your sister is 3/6 or 1/2.

To find the probability of getting 5 from both your mom and sister, we multiply the individual probabilities together: 1/3 * 1/2 = 1/6.

So, the probability of getting 5 is 1/6.
